PROJECTION-TYPE PARTIALLY DUAL-STRUCTURED STENT

摘要

Disclosed is a partly projected double-walled stent. Provided is a technique for allowing a stent to be easily secured in a conduit in a human body by a protrusion coupled to a body. According to the stent, first and second ridges of the protrusion are crossed and projected to be inclined in opposite directions, and thus the partly projected double-walled stent is rigidly secured in the conduit in the human body without being displaced in the left and right directions by an external force. Also, the number of protrusions can be adjusted according to circumstances so as to simplify a manufacturing process and reduce manufacturing costs. Further, a cover coupled to the body prevents a lesion portion from penetrating into the partly projected double-walled stent, thus preventing re-stenosis caused by the lesion portion.

主权项

1. A partly projected double-walled stent, comprising:
a body having multiple wires woven to be crossed, an outer circumferential surface formed in a mesh pattern, and an interior formed in a hollow cylindrical shape; and at least one protrusion coupled to the outer circumferential surface of the body, and projected along the outer circumferential surface of the body.
